Laurent,
I had the same issue on Safari, but not Firefox. I fixed the problem
by going to:
safari > preferences > privacy > block cookies > changing the setting to "never"
I think this behavior results from the way Drupal Gardens implemented
custom domains. You can still access the site without changing your
cookie settings on Safari here:
http://privly.drupalgardens.com/
but if you submit any links to the site, make sure you change your
link to:
http://www.privly.org/YOUR_LINK_HERE
Did that fix the problem?
